Review on traffic engineering and load balancing techniques in software defined networking

Abstract

Traffic Engineering-TE deals with the major issue in the arena of the computing and network. There will be so many failures in and out of the network as traffic demand increases. Thus there are many techniques available for countering this problem. Many researchers also proposed a number of traffic engineering techniques to be successfully deal with the issue. But all these tactics and techniques that have been suggested for traditional methods. Such methods are difficult to implement or there is no effective way to implement. Research communities have been working extensively on methods for traditional networking structures that allow the network to adapt to changes in traffic patterns. So here comes new ideology in which there is good manageability of network. Each time network stages will be varied and also these changes should be well managed for the good traffic outcomes. These are done through the modern age of networking SDN (Software Defined Networking), as it makes optimum use of resources in the network. We can have a quick glance where the techniques of traffic engineering (TE) perform for the traditional networks and even the new concept of networking known as SDN.
